"OMEGA has announced the launch of the Seamaster Planet Ocean Liquidmetal® Limited Edition, the world’s first watch to bond ceramics and Liquidmetal®. It is the 42mm version.
Swatch Group researchers collaborating with OMEGA’s product development team have created a striking ceramic diving bezel whose numbers and scaling, made of the Liquidmetal® alloy, appear in stunning silvery contrast to the black ceramic background. The colour of the ceramic dial perfectly matches that of the bezel. The result is an aesthetic wonder only made possible by several new and innovative processes.
The remarkable world premiere is being launched in a limited edition of 1,948 pieces in honour of the year OMEGA launched its popular Seamaster watch line."
So, sounds like a normal 42mm PO case with the ceramic/liquidmetal bezel and ceramic dial. No PVD/DLC from what I read.
